Introduce xdp frags support to veth driver in order to allow increasing the mtu over the page boundary if the attached xdp program declares to support xdp fragments. This series has been tested running xdp_router_ipv4 sample available in the kernel tree redirecting tcp traffic from veth pair into the mvneta driver. Changes since v4: - remove TSO support for the moment - rename veth_convert_skb_from_xdp_buff to veth_convert_skb_to_xdp_buff Changes since v3: - introduce a check on max_mtu for xdp mode in veth_xdp_set() Changes since v2: - move rcu_access_pointer() check in veth_skb_is_eligible_for_gro Changes since v1: - always consider skb paged are non-writable - fix tpt issue with sctp - always use napi if we are running in xdp mode in veth_xmit Lorenzo Bianconi (3): net: veth: account total xdp_frame len running ndo_xdp_xmit veth: rework veth_xdp_rcv_skb in order to accept non-linear skb veth: allow jumbo frames in xdp mode drivers/net/veth.c | 192 +++++++++++++++++++++++++++++++-------------- include/net/xdp.h | 14 ++++ net/core/xdp.c | 1 + 3 files changed, 146 insertions(+), 61 deletions(-) -- 2.35.1
